Need help solving these four problems. I can't open .jpg or any images that my phone can't access. But I can see pasted images from far so don't write too small please.

Find the equation of the line tangent to the function S(x ) =- sin - at x =0 1 + cos.x (+) - air "'s , then find S'() If f(x) = sin^-1 x, then find f'(x) D.) C.) 14 dx' +1 x52 Let fix) be the function defined above, where c and d are constants. Find the value of c & d that make fix) differentiable at x = 2. 10) Find f'(x) for f(x) = Inx(tanx)
